Using the trigger timer on your FNIRSI FNB48P Type-C USB Tester is straightforward. First, connect the USB tester between your charging device and the charger. The timer automatically activates and begins tracking once charging starts, indicated by "RUN" on the display. The timer continues until charging ends, either naturally or if manually stopped, then it displays "STOP." If your device utilizes a fast charging protocol like QC2.0, the display will show the protocol, such as "QC2.0." If no fast charging protocol is active, the display will show "NONE." The load resistance value shown below the timer is informational only. For comprehensive details, consult the FNIRSI FNB48P Type-C USB Tester user manual.
